Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • This application claims the benefit of U.S. Provisional Application No. 61/414,944, filed 11/18/2010 .
  • BACKGROUND
  • The disclosed invention is directed toward an improved construction for a reinforcing fabric for belts.
  • Recent developments in high tension abuse resistant conveyor belt fabrics have created fabrics which are too thick and rigid to be used in multi-layer constructions. They either have too little crimp in the warp to allow multi-ply construction or are so thick the distance between two plies creates longitudinal flexibility and troughing issues. This invention takes the positives of the high tension fabrics and combines them with the benefits from using lighter weight conveyor belt fabrics.
  • Most high tension/abuse resistant fabrics being produced today use a straight warp tension member. This straight warp yarn has 0-1% crimp which limits the ultimate elongation of the finished belt, but also makes it very rigid if produced in multi-ply constructions.
  • High volume conveyor belt fabrics are produced using a plain, crowfoot, or twill pattern. These weave patterns can produce fabrics with 3-10% crimp. They excel in multi-ply conveyor belts but create too much stretch and poorer abuse resistance than their straight warp counterparts.
  • This invention takes a crowfoot or twill pattern and improves its stretch and abuse characteristics by creating 2 layers. The two layers induce a moderate amount of crimp, 2-5%, which allow the fabric to be used in 2, 3, or 4 ply applications. They also improve the abuse resistance over standard weave patterns in that the warp yarns are protected by the weft yarns. The exposure of the warp yarns is kept to a minimum by the unique weave pattern.
  • SUMMARY
  • In accordance with the present invention, a reinforcing fabric for a belting is disclosed. The reinforcing fabric is a composite fabric which provides the belt with superior properties such as high rip resistance, transverse tear resistance, impact resistance, anti-fraying, and flexibility. In accordance with the present invention, the composite has two layers, the weft yarns have a corresponding binder, and there is a top warp yarn which covers some of the top weft yarns, and a bottom warp yarn which covers some of the bottom weft yarns.

    DETAILED DESCRIPTION Definitions
  • "Binder Yarn" denotes yarn that is used to bind together different yarns in a fabric.
